It's very sexy overall, but the trackball is an eyesore to me, sorry. Great choice in monitor/hardware. How hard would changing the JAMMA board be?
Yeah, I kinda agree on the trackball, although you kind of get over it pretty fast. The main problem was that I built the unit out of 16mm MDF, which is thin when you start routing out mount points for trackballs. It's perfectly strong enough overall, but the control panel could have been improved if I'd put a perspex layer, metal plate, etc in the design. I had to put that giant metal plate on the top because it wouldn't have had enough strength any other way with my current design (gloss painted 16mm thick MDF). Maybe I will retro-fit something nicer one day. I'm jealous of the very cool control panels others have built.
I used JAMMA wiring through the whole box. The control panel is hinged at the front with two traditional arcade latches at the back. When you lift it up you find the 60-in-1 vertically mounted, a nice little 12v amp, power supply, and the back of the coin-mech etc (and coin container). Not too hard to change boards, but you wouldn't fit a full-sized arcade board in there the way it's currently designed. It would have been easy enough to run the wiring from the back of the box and to have room for full sized boards, but I always saw this as a multi-cab. Where it is at the moment I can easily access DIP switches etc.
If you remove one of the speakers in the side, you can access the bolt that holds the gas lift in place. Then you can swing the monitor all the way up and over to access the inside of the box, so it wouldn't have been terrible to have mounted the board inside somewhere.
